Saccharase refers to an enzyme that catalyzes the hydrolysis of sucrose into glucose and fructose. There are a variety of synonyms for saccharase, including sucrase, invertase, beta-fructofuranosidase, beta-d-fructofuranoside fructohydrolase, and alpha-d-glucoside fructohydrolase. These terms are commonly used interchangeably within the scientific literature and research communities. Sucrase is the most frequently used term to describe the enzyme responsible for breaking down sucrose in the digestive system of animals, while invertase is a more specialized term used to describe the same enzyme in plants and fungi. However, all of these synonyms refer to the same enzymatic function of breaking down sucrose into its constituent parts.
